Meanwhile, the doyenne of the Radio 4 programme Woman’s Hour, Jenni Murray, herself a campaigner on issues relating to women’s health, wrote a piece for The Daily Mail detailing her shock and horror at the material she found on the Mumsnet discussion boards.

In particular she was upset by a thread entitled ‘Just wondering how often people have sex when you’ve been together and have kids. ’ and another written by a poster who was considering engaging in a threesome.

The discussion thread attracted hundreds of posts, but 100% of posters assured her that, no, this was not normal behaviour.
